  <div>
   <div class="section">
    <h4 class="sectiontitle">Symptom</h4>
    <p>During resource scan or backup and restoration, only a job failure message is displayed and no other error message is displayed.</p>
    <p></p>
   </div>
   <div class="section">
    <h4 class="sectiontitle">Possible Causes</h4>
    <p>When the load of a CNware management node or compute node is heavy or the number of resources is large (depending on the hardware capability of the compute node), the CNware interface responds slowly. As a result, the backup software fails to invoke the interface due to timeout.</p>

    <p id="EN-US_TOPIC_0000002164659306__en-us_topic_0000002164630552_p1389433101916">The following operations assume that the default installation directory of the client is <strong id="EN-US_TOPIC_0000002164659306__en-us_topic_0000002164630552_b83801030151211">/opt</strong>. Replace it with the actual installation directory of the client.</p>
   </div>
   <div class="section">
    <h4 class="sectiontitle">Procedure</h4>
    <ol>
     <li><span>Use PuTTY or SSH to log in to the host where the CNware VM client resides.</span></li>
     <li><span>Run the following command to check the connectivity between the host where the client is installed and the production environment. In the command, <em>xxx.xxx.xx.xx</em> indicates the IP address of the CNware management node.</span><p></p><pre class="screen">ping <em>xxx.xxx.xx.xx</em></pre> <p></p></li>
     <li><span>Run the <strong>cat /<em>opt</em>/DataBackup/ProtectClient/ProtectClient-E/log/Plugins/VirtualizationPlugin/VirtualPlugin.log | grep "Http send request failed. Error is28"</strong> command to query failure logs.</span><p></p><p>If any command output is displayed, go to <a href="#EN-US_TOPIC_0000002164659306__li59871696516">4</a>. Otherwise, contact technical support engineers.</p> <p></p></li>

     <li><span>Find the value of <strong>ConnectTimeOut</strong> and <strong>TotalTimeOut</strong> under <strong>General</strong> and increase the value of <strong>TotalTimeOut</strong>. <strong>ConnectTimeOut</strong> and <strong>TotalTimeOut</strong> indicate the timeout interval for establishing an interface connection and the total interface timeout duration, respectively.</span><p></p>

       <div class="notebody">
        <p>Generally, you need to only increase the value of <strong>TotalTimeOut</strong>. If the resource scan or backup and restoration jobs fail to be executed after the value of <strong>TotalTimeOut</strong> is increased, increase the value of <strong>ConnectTimeOut</strong> and try again.</p>
       </div>
      </div> <p></p></li>
     <li><span>Run the <strong>sh /</strong><strong><em>opt</em></strong><strong>/DataBackup/ProtectClient/Plugins/VirtualizationPlugin/stop.sh</strong> command to restart the plug-in.</span></li>
     <li><span>Perform resource scan or backup and restoration jobs again.</span></li>
